Just bought a lovely 2011 xk portfolio convertable with only 36,000 miles, very excited. I need a certificate of Conformity and Jaguar have sent a list of requirements and form to complete, looks straightforward. However they need photos of 3 VIN number locations, on front or should I say under front window, done. On passenger door frame to also show weights etc, done. On the Chassis....PROBLEM, search as I may, books, internet etc I cannot find any reference or see myself a VIN on the chassis. Can anyone help?
